Do you mind joining me for a short Bible study in order to show that the book of Enoch is a great deception that works to prey on minds that have not yet had a personal and prayerful study of the Bible and the Bible alone?

To the law and to the testimony: if they speak not according to this word, it is because there is no light in them. Isaiah 8:20

If anything in the book of Enoch is not in harmony with the Bible, then there is no light in it.

For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. Matthew 22:30

The very beginning of book of Enoch describes "watchers" as procreating angels, yet angels neither marry nor are given into marriage. Angels are non-procreating beings. This alone dismisses the entirety of the book.

There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown. Genesis 6:4

Now for the sake of having a little longer Bible study, the book of Enoch mentions "giants" or "nephilim", but Biblically, the word for "giants", the masculine noun "nāp̄îl", properly represents a person. Expanded from the root word "nāp̄al", nephilim represents a people who have "fallen away".

And there we saw the giants, the sons of Anak, which come of the giants: and we were in our own sight as grasshoppers, and so we were in their sight. Numbers 13:33

The only other place it is used is in Numbers 13:33 when describing the people of Anak, an apostate people who had fallen away from the requirements of God. So while the word "nephilim" physically represents stature, is spiritually represents apostasy.

This apostasy takes after Cain. The race of Cain, spreading from the place of their first settlement, dispersed over the plains and valleys where the children of Seth had dwelt; and the latter, in order to escape from their contaminating influence, withdrew to the mountains, and there made their homes. So long as this separation continued, they maintained the worship of God in its purity. But in the lapse of time [...] The children of Seth, attracted by the beauty of the daughters of Cain, displeased the Lord by intermarrying with them.

So God created man in his own image, in the image of God created he him; male and female created he them. Genesis 1:26-27

Man was originally made in the physical resemblance of God. Even until the times of Abraham, the stature of man still resembled the likeness of his Creator (Genesis 18:1-2), and therefore there would be no distinguishing the appearance of an angel from that of certain men.

And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the Lord. And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the Lord had respect unto Abel and to his offering: Genesis 4:3-4

The book of Enoch encapsulates the imaginations of Enoch the son of Cain. It takes after the imagination of Cain in giving a “better” offering in the place of what Abel was told to offer. This is very evident when considering that the worship system of Cain came to be known sun worship (Genesis 4:16, Ezekiel 8:16), and that the writings in the "Book of Heavenly Luminaries", which is a part of the book of Enoch, involved sun, moon, and star worship.

And lest thou lift up thine eyes unto heaven, and when thou seest the sun, and the moon, and the stars, even all the host of heaven, shouldest be driven to worship them, and serve them, which the Lord thy God hath divided unto all nations under the whole heaven. Deuteronomy 4:19

And astrological worship will always be a form of Satanism practiced under the name of Baal worship:

And they left all the commandments of the Lord their God, and made them molten images, even two calves, and made a grove, and worshipped all the host of heaven, and served Baal. 2 Kings 17:16

Therefore, no different than the book with which it is written in, the "Book of Heavenly Luminaries" is nothing more than the counsels of astrologers and stargazers:

Thou art wearied in the multitude of thy counsels. Let now the astrologers, the stargazers, the monthly prognosticators, stand up, and save thee from these things that shall come upon thee. Isaiah 47:13

Such books are meant to captivate the imaginations of the heart and stick the head in the dirt while the body imagines itself as being elevated upwards toward heaven. So therefore lift the eyes up and away from such nephilim worship:

Lift up your eyes to the heavens, and look upon the earth beneath: for the heavens shall vanish away like smoke, and the earth shall wax old like a garment, and they that dwell therein shall die in like manner: but my salvation shall be for ever, and my righteousness shall not be abolished. Isaiah 51:6

And turn them towards the Creator of the sun, the moon, and the stars:

By the word of the Lord were the heavens made; and all the host of them by the breath of his mouth. Lift up your eyes on high, and behold who hath created these things, that bringeth out their host by number: he calleth them all by names by the greatness of his might, for that he is strong in power; not one faileth. Psalm 33:6, Isaiah 40:26

Since you have time at work to listen, might I recommend something? I feel that this 36 episode lecture-series, which is based on the Bible and the Bible alone, will bring you very near to the Word of God as directly written in His book. These episodes may be exactly what you need and what you are looking for (it will even answer the question of music for you):
